6.1 General Notes
Use Blue Loctite on all fasteners.
CAUTION - DO NOT ALLOW LOCTITE TO COME INTO CONTACT WITH PLASTIC SURFACES.
Chemical reaction occurs causing the plastic to prematurely deteriorate.
Avoid installing the BPU upside down.
There are some pre-cut holes in the mounting bracket to assist with fastening.
Usual installation methods include hose clamps, directly bolting to plant, or magnets.

6.4 Tips
If BPU is installed vertically, sunshade is not necessary.
Try to have logo upright (Sensor cables are hanging towards ground) to prevent water ingress through cable connectors
Remove flaps on BPU to access mounting holes.
If possible, check if the BPU software needs to be upgraded and commence upgrades while preparing plant power and/or routing cables to save time.
